Greetings, I have no experience with old books, publications, or ephemera of any kind, but in my possession are 5 US Department of the Interior Geological Surveys ranging from 1912 to 1930's. I do not know how to assign a monetary value to any of them at all. Any help appreciated. The ones I have are: Bulletins: 498 - Alaska, 1912 589 - Vermont, 1915 587 - Alaska, 1915 797-F - Alaska, 1929 Professional Paper: 172 - Gold Quartz Veins of the Alleghany District of California, 1932 I have all the color maps/plates that come in the envelopes attached (I think?). Pictures can be provided if you want.
Looks like the USGS has digitized a lot of these and they are free online. Something to consider. Bulletins: https://pubs.er.usgs.gov/browse/Report/USGS Numbered Series/Bulletin/ Professional Papers: https://pubs.er.usgs.gov/browse/Report/USGS Numbered Series/Professional Paper/ All of their numbered series: https://pubs.er.usgs.gov/browse/Report/USGS Numbered Series/ U. S. Government reports are free to the public. I'm not sure there is much of a market for the printed ones, but it's possible that somebody would want them since you have the color plates and maps already printed out. (They are also available in PDF form through the links above.)
You may be able to find comparative examples on abebooks.com. Collectors might be interested in the plates.
Thanks for the replies, I did take a look at abebooks and it doesn't look too much different than the smattering of ebay listings sold and unsold, at least as far as the federal stuff is concerned. I'll likely use the links figtree put up mostly to verify the completeness of the attached plates and market them based mostly on that. Thanks for the help guys
